D-K6L9

D-K6L9 is an all-D enantiomeric peptide enriched in lysine and leucine residues arranged for amphipathic helix formation. D-configuration confers strong resistance to proteolysis while preserving membrane-interaction potential. Researchers explore its folding, aggregation, and antimicrobial-like properties in vitro. Applications include D-peptide design, stability studies, and membrane-active motif development.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
